Take-home exam 2 tips

  • Make sure your take-home exam can render!
  • To be extra cautious: render after after starting a new code chunk! Do this every time!
  • If you aren’t sure how to complete a problem, break it into sub-steps that you do know how to complete.
  • Reference your AEs!

Project

  • Review peer evaluations left by your peers, implement updates as you see fit, close the issue once you review them.

  • Have a clear plan for who is doing what, open issues on your repo, and assign them to individuals who can then close the issues as they finish a task.

  • Schedule at least one team meting between today and your presentation to practice your presentation together.

Recap

  • Represent percentages as parts of a whole
  • Place variables representing time on the x-axis when possible
  • Pay attention to data types, e.g., represent time as time on a continuous scale, not years as levels of a categorical variable
  • Prefer direct labeling over legends
  • Use accessible colors
  • Use color to draw attention
  • Pick a purpose and label, color, annotate for that purpose
  • Communicate your main message directly in the plot labels
  • Simplify before you call it done (a.k.a. “Before you leave the house, look in the mirror and take one thing off”)
